I am new to sharepoint and currently using Sharepoint Foundation 2013. I created sites, subsites and multiple Document libraries in lower level subsite and enabled navigation treeview. I can see nice treeview as per my requirement.
Now, my requirement is to add Tooltip in each item (Document Libraries) and want to display 'Description' as a Tooltip. Currently it is displaying Document Library Name in a tooltip. Is there any trick to do it through Sharepoint Designer? I Cannot use Custom Webparts as of now.
